Optical sapphire window piece

Optical sapphire window piece

The window sheet is a biplanar optical glass, usually used as a protective window for sensors and CE detectors. The window slice does not change the magnification of the system. Substrate materials include various optical glass, K9, UV fused quartz, fused quartz and calcium fluoride (CaF2), magnesium fluoride (MgF2), zinc selenide (ZnSe), germanium (Ge), silicon (Si) and other materials.

Provide window film coating services, anti-reflection film, high reflective film, spectroscopic film, metal film and other optical coating. The wideband antireflection film can be used in ultraviolet, visible, near infrared and mid-infrared bands.

Optical sapphire window piece

Due to the high quality artificial sapphire crystal materials within 0.20 ~ 5.50 mu m band has good pervious to light, infrared transmittance almost does not change with temperature, the ultraviolet and visible light transmission rate is also high, therefore it is commonly used as a substitute for other optical components, optical materials infrared optical window film, and is widely used in the infrared and far infrared military hardware, Such as: used in night vision instruments such as infrared and far infrared sight, night vision camera and satellite, space technology, instruments and meters, and is used as the window of the high power laser, all kinds of optical lens, optical window, UV and IR window, lens, low temperature experimental observations of the mouth, with a high precision instruments and meters in maritime aerospace applications get sufficient fang.

Uncoated sapphire has excellent surface hardness and a transmittance range from ultraviolet to mid-infrared wavelength region. Sapphires can only be scratched by a few other substances. The uncoated substrate is chemically inert and insoluble in water, common acids or bases at temperatures up to about 1000°C.

Sapphire has high temperature resistance, good thermal conductivity, high hardness, infrared permeability and good chemical stability. It is widely used in many fields of industry, national defense and scientific research (such as high-temperature resistant infrared window, etc.). High precision sapphire substrate

Sapphire window piece basic features:

1. The spectral range is 150-3500nm;

2, high strength surface hardness;

3, scratch resistance, high temperature resistance;

4, chemical inertia, acid resistance, alkali resistance.
